Ejay, Creative Commons License By Anne Marie Helmenstine, Ph.D. Experimental error is not relative - it has the same meaning to everyone. So, unlike real scientific research where the answer is not known, you are performing experiments that have known results.

What is her experimental error? Albert has an error of 1.1% in his experimental density for aluminum. Solve for the measured or observed value.Note due to the absolute value in the actual equation (above) there are two solutions. Please try again later.
